High-yield chemical syntheses of phosphoramidite building blocks of the four arabinonucleosides aUrd (1), aCyd (2), aAdo (3), and aGuo (4), suitable for (3′–5′)oligoarabinonucleotide synthesis are described. The problem of 2′-hydroxy group protection was solved by introduction of the versatile 2-(4-nitrophenyl)ethoxycarbonyl (npeoc) residue, which was also used for aglycon protection.
